i have an NW-HD1 and have encountered a problem. i reinstalled xp to freshen up my computer, and when i loaded the new sonicstage i got an error message relating to copyright. it said to avoid this i could either authorize the player or computer, or delete all the files on the player. As i had them on my computer i decided to delete the files off the player and put them on again, however when i tried this i got a message saying that the files were either not the right format, or copyrighted. these were the same ones that went on the HD1 with the old sonicstage version. i have managed to put a few albums on but only ones that were ripped after windows was reinstalled. i could re-rip every cd but really cant be bothered. ive tried Ryzirs software suggestion, i really need an old version of sonicstage (2.1 or 2.3 would be great) or im open to new ideas if anyone has any!!
